Testing the Free Horsepower Mods for the Fiat 500 Abarth

[@comixxpro1]

I have found several instructional videos for the boost leak mod and the waste gate actuator adjustment. I have to say that this video is, by far, the easiest to follow. I followed this video for both mods on my 2013 Abarth 500 and was shocked at how much difference it made. I have VERY little turbo lag now. Thank you for such a well done and easy to follow video. Keep up the good work.

Holy crap, this is one of the funniest home mechanic videos I've ever watched, AND I actually learned something. Just picked up Abarth #2 and I may have to do these mods myself. Any emissions issues with the Boost Leak fix?

Dude, this video was EXCELLENT! I am enjoying researching the abarth right now as i look at daily drivers that i can occasionally autocross. Right now im considering this abarth and the velociter n. The quality of this video was uncommon, you did a great job. Do you still have your abarth, and if you could go back in time would you still buy it?

[@EveryOtherFridayOff]

ThePreppersBunkerOutdoors I still own and still love the Abarth. I would absolutely buy again. If you are looking to buy the best autocross car, then there are probably better choices if winning is what matters to you. With an Abarth though, you get a great deal on the best sounding, Italian, most ridiculous car on the grid. I love that I get to drive a crazy little race car to work.

[@gregoryharper6401]

@@EveryOtherFridayOffmy question is some what related I have a 2013 Abarth I replaced the engine from a low mileage, 13K, 2013 donor that had been sitting for a year or so. It has no codes but the cap and O2 monitors won’t reset. At installation I installed new plugs, coils, O2s, crank position and knock sensors. I’ve driven 2000 miles with several cold starts The car is stock except for an ATM FMIC and ATM fender well CAI

[@upat3am35]

That was funny asf when u said what it took to take off the two last bolts 😂

[@CrazyForCashews]

Fingers crossed you post a video on that overly elaborate boost leak fix that'll prevent any CELs!

[@BrockGrimes]

Look at the boost between the initial run and 2nd run...that 2nd run it's on boost longer at a solid 15 and the 3rd it bumps to a 16 and still holds. Interesting it stayed on boost longer even with the IAT higher on 2nd run vs 1st run.

[@FOX11GUY]

One full rotation of added preload. But you said it now opens sooner?

[@EveryOtherFridayOff]

So I'm sitting here trying to figure this out. As you can see on the video, there wasn't a whole lot of difference in what pressure actuated the wastegate. Logically my description has to be backwards, right? Opening sooner should leak easier and be slower. But that is what I said, and I'm faster. I tried re-watching the guage in the video, and I honestly cant tell if my description was right. The simplest explanation is that I got the description backwards in the video, and the WG is opening a little later (at a higher pressure). Its been so long, I'm not sure if I screwed up, or if there is something I'm missing. The only reason I'm not going to jump on "I got the description wrong" is that I wasn't trying to over-preload the WG, just bring it to factory spec. So while counter intuitive, I may have just made an extremely smart engine "happier" rather than cheated preload to avoid a WG leak.

[@davidclark8303]

Yours is the only vid where the wastegate actuator doesn't get disconnected from the wastegate then turned by hand; never knew it could be done just twisting it like that.

[@jamesp2293]

I did the boost leak mod as you described it and I am getting a P1CEA fault code now. Can you offer guidance?

[@stubert38]

Awesome video thank you!!

[@anmarenja]

Love your videso, so informational. I do have a question about your injen intake. I know you don't have it installed anymore, but I was wondering if you had any "whistle" sound under full throttle? I installed mine about a week ago and have the whistle is extremely loud. I checked for intake leaks, and re did the install, put hose clamps on everything I could. The noise is still there. Any suggestions?

[@EveryOtherFridayOff]

I never had anything like that. Hard to imagine what it could be. It’s not turbo spooling whistle is it? If you’re used to stock, turbo noises will be a little louder. Another idea would be to see the difference between full throttle on the road vs full throttle out of gear in the driveway.

[@anmarenja]

You can't hear it under full throttle in neutral. And I don't think it's just the turbo spooling up, it's a very high frequency whistle. It's really annoying actually.

[@fillefilander]

Does this only apply to the Multiair? Or does it work for the T-jet? What does the second mod actually do?

[@EveryOtherFridayOff]

I have no idea about the T-jet. The second mod plugs a boost leak

[@fillefilander]

@@EveryOtherFridayOff yes, but exactly what is leaking?

[@EveryOtherFridayOff]

Mattias Filander the Venturi is hooked to the charge side of the turbo. The compressed charge from the turbo is what is being used to drive the Venturi. So it is literally a boost leak being plugged

[@fillefilander]

@@EveryOtherFridayOff ok, but what function has the venturi then?

[@EveryOtherFridayOff]

Mattias Filander The Venturi creates a vacuum which is used to draw fuel vapor from the EGR canister. On most cars, normal crankcase vacuum is used for this. On our cars, which stay in boost for long periods, it was thought not to be enough. This mod eliminates the Venturi, and plugs the egr directly into the intake

[@laurentcernat2832]

Did it get rid of all the hissing sound at high rpm coming from the intake?

[@mcappleish]

Like all your videos! Got a question about the EGR mod. The EGR use manifold vacuum under low torque request(throttle almost closed). This is how emission is reduced upon cold start. During wide open throttle, manifold has no vacuum but boost, EGR valve should stay closed, so you won't lose any boost. I don't know much about this but I can't see when could you lose boost without this mod. Can you shed some light?

[@mcappleish]

never mind..figured it out

[@the-real-zpero]

@@mcappleish can you explain it to me? I bought a used Fiat 500 Abarth and the EGR tube is suspiciously missing. So I want to know if I should buy the missing parts and return to stock.

[@upstatetyler2380]

May sound stupid, but how is that a boost leak fix? What does that do to the vacuum?

[@EveryOtherFridayOff]

The vacuum is driven by a Venturi. The Venturi is driven by boost. That boost travels through the Venturi, and is dumped into the intake. That boost going into the intake instead of the engine is the “leak”. In this mod, that leak is plugged, so the boost leak is plugged, but now the vacuum is gone. We hook up the EGR to the intake, which has some vacuum when you are off boost. So for most city driving, that works well. For long highway trips, you are sitting in boost for a long time, and that can generate P1CEA codes when a vacuum is not detected often enough

[@upstatetyler2380]

Sounds like something you shouldn't do then. Everyone gets on the highway eventually

[@EveryOtherFridayOff]

@@upstatetyler2380 Well, I still haven’t found anyone who has had any actual problems from the code. And the performance gain is actually significant. So if occasionally resetting a code is worth the gain to you, do it. If not, don’t. To me it’s worth it.

May I ask what induction kit your have on this Nd the ducting for it? Not seen this in the UK or Europe.

At the time of this video, I had a garbage product that came with the car. I doubt it was any better than stock. I have since moved to an ATM fender well intake (see intercooler video) which is much better.

what intake do you have? do you like it? thanks

[@snowcold903]

When adding extra horsepower to cars, you should also consider if the transmission and engine can handle the added horsepower. But this Fiat is smaller and lighter than most cars so that maybe be a great opportunity to add some more horsepower. my car is a little bigger than the fiat 500 with 98 horsepower and i think its fast enough for me, had it been bigger and heavier then i think it would have been slower.

[@francescosantangelo6614]

In italy and in Europe fiat dont use a multiair turbo on 500 abarth ....but use a motor t-jet turbo .....140 cv or 160..or 180 cv this motor is more strong and durable than multiair turbo

[@hugolafhugolaf]

Could you share how you test the wastegate and with what kind of gauge?

[@EveryOtherFridayOff]

The wastegate has a single airline running to it. Disconnect this, plug in your own airline to the wastegate. I added a tee to this line. On one side of the tee, I hooked up an accurate pressure gauge (1 psi matters). The other end was hooked to my compressor. I used a spray nozzle on the compressor so I could give quick blasts of air

[@andrejdni]

would the last mod tamper with smog tests? (california)

[@EveryOtherFridayOff]

Not certain.

[@JustCreateYou]

Is the eurocompulsion boost leak instructions do the same thing as this ? Or one is better then the other ? 🤔

[@EveryOtherFridayOff]

If I recall, the EC instructions do not tie the EGR back into the intake, but just leave the exhaust open through a filter. That seems less good to me. The EGR needs a vacuum to evacuate it. The intake isn't always vacuum, so its not perfect, but still seems better than atmosphere. What I showed was the Tork version. I think this, along with using a Y rather than a T, is less prone to check engine lights.

[@JustCreateYou]

@@EveryOtherFridayOff awesome and does it have to be a y fitting ? Because it's hard to find in San Antonio. I have to order and by the time because this whole coronavirus stuff going on... If no to a t fitting why not ? Just wondering

[@EveryOtherFridayOff]

The y theory comes from a long thread on fiat500usa forum. The idea is that a smooth flow is going to reduce check engine lights. I ordered mine from amazon. The small power gains should be identical with a t, but the thinking is that check engine lights will be more frequent.

Now you have the ole wheels turning, (l0l) so the system is sensing an evap flow/leak? Soooo, being this is an evap code it shouldn't derate or cause any performance issues?

[@laplantski]

@@EveryOtherFridayOff Or is reading something funny from the venturi?

[@EveryOtherFridayOff]

@@laplantski Right. Code is from not enough vacuum. If the evap canister was completely blocked off or seeing no vacuum at all, it would eventually fuel soak and be destroyed. I don’t think this mod actually risks that, but since our vacuum is coming from the intake rather than the Venturi, it’s not consistent enough for the ecu. Especially sitting on a little boost for long periods on the highway

[@frontwheeldrip4253]

I did this mod and my car ran for about 16 seconds then a loud blow happened and now no boost. Worked it back to factory and still no boost. Something bad has happened because of the re-route around the Venturi actuator

[@EveryOtherFridayOff]

Are you sure you are back to factory? Sorry to hear you are having problems. I haven’t heard any issue like this before. Fiat500owners.com has helpful people and information on loss of boost pressure troubleshooting. A loud pop sounds like a hose popping off. Unfortunately, quite a few connections you need to check are pretty hard to get to

[@frontwheeldrip4253]

Every Other Friday Off a few hours of searching returned no answers for where the boost leak could be. I’m thinking it has to do with one of the tubes I was touching/ working with. In the video, you have an OEM “T” fitting with two ends capped off. This line runs straight from the intake manifold, if I’m not mistaken. To me, I think it popped off the intake plenum leaving a large hole for boost to leak out of. I’ll have to check again tomorrow to make sure all the lines are plugged. Car not throwing codes. Extreme limp mode. Will not go past 60mph. Very loud whining noise upon acceleration, like running an open turbo

[@EveryOtherFridayOff]

That would be the most simple explanation. That “oem t” is the Venturi. That line should be the only charged line you were messing with. Unfortunately, battery and battery tray need to be removed to get to the far side. Good luck, sorry you’re having problems. I’d love to hear back when you get it fixed.

[@frontwheeldrip4253]

Every Other Friday Off from my research, it doesn’t seem like that’s where the problem is. The line I’m talking about routes directly to the back of the intake plenum, at a 90 degree bend (not the line to the air intake ducting). I have also removed the battery tray before and can confirm that the charge pipe is in 100% functioning condition, as well as the lines that lead to the charge pipe underneath the battery tray. They are all in good shape. I still haven’t been able to get back around to it, but I still believe my error to be that line that routes off the back of the intake plenum. Kind of hard to see, but very easy to feel with ur hands. I will get back to you on Monday with more research. Do you have a more direct method I can reach you at? This problem is really eating away at me. Would like to know ur thoughts.

I don't have enough miles on it to say, and I haven't heard that. I would think the bigger concern would be going lean under a "higher" boost. However, peak boost really didn't change much, the boost just came in sooner. So I imagine the ECU is handling AFR's as normal. I can't think of how else this would affect AFR's.

Felipe Lopez: This is a horribly controversial topic in the Abarth community. I think you can get a general agreement that a true ecu tune is going to be better than any piggy back tuner. So that leaves eurocompulsion, Tork, and OFT as the generally agreed “best” options for the North America, multiair Abarth. The animosity between Fans of Tork vs fans of EC is really bad, with almost every discussion turning into a flame war. It’s generally agreed that OFT is making less power than the other 2.
